[PATCH] UHCI: use integer-sized frame numbers

Browse Source 
This patch (as687) changes uhci-hcd to keep track of frame numbers as
full-sized integers rather than 11-bit values.  This makes them a lot
easier to handle and makes it possible to schedule beyond a 2-second
window, should anyone ever want to do so.
